Application filed June 11, 1925. Serial No. 3s,446.

of a plurality of chainsadapted to pass. across the face of the tire and around the same, having shackles at their extren'iities which are engaged with the rim of the wheel to thereby prevent the the from further blowing out or bulging under the pressure deformation to which the tire is subjected.

A. further object is to provide a device of this character in which the chains are provided with shackles which are detachable a-nd'reversible so that when one face oil the chain forming the body of the binder has become worn unduly, the shackles maybe reversed with, relation vto the chain so that the unworn portion or face of the chain may be utilized. I Y

My invention 18 1llustr'ated 1n the accompanying drawing, wherein Figure 1 is a fragmentary side" elevation of a tire showing my tire binder in place thereon; y

Figure 2 is a section on the line 2 2 of Figure 1;

Figure 3 is a longitudinal seetionth'rough the shackles engaging the rim and through the end links; v

Figure lis a like view to Figure showing the end links shittedfto a position permitting the removal of the pin; Figure 5 is a section on the Figure 3;

Figure 6 is a section on the line 6-6 01 Figure 4, both or the last named figures showing the endlinks and their flattened line 55 of Referring to this drawing, it will be seen that my improved binder consists of two parallel chains 10 shown as of the twisted link type such as commonly used for the 'ordinary cross skid chains, these chains terminating in the links 11, each link being formed of a single piece of wire bent upon itself to form a bight 12 which engagesthe adjacent link,', and the two arms of the bent wire extending down parallel to each other at 13 and being bent around to form an eye.

Coacting' with each chain 10 is a shackle,

being doubled upon itself and bent so asto iorm the bill 16, the shank 1'7 and the eye portion. "lhis eye portion, where the two thicknesses oi? metal are separated, is dchi'ormed to prov de a transversely exteye or eyes. This strip previous to b it into the hook form is slottcdat 18 and this slot intersects the eye portion otthe strip so asto provide two eyes 19 on each side of the slot? 18. These eyes 19, as shown are somewhat ovoid in cross section, and at tached to the shackle 15, as for 1I1St2..nCG,'l)y

beingsold'ered thereto is'thetransverse resilient bar-20 which is disposed so as to (3X tend across the slot 18 at the base thereof justabove theend of. the slot.

Dis osed throu 'h the e es13 and 19 is a I pin 21. This pin is designed to engage the shackles-and links 11 off both chains 10 and the pin 21 inward of each end isforined with an enlarged cylindrical portion 22 sepa rated by a reducedportion 23 which has a diameter equal to the normal diameter of the designated generally 15, this shackle being formed oi a single str p of metal, the strip pin. The enlarged portion 22 fits within a the eyes 14L, while the reduced portions 21 and 23 (it within theeyes 19. The bills16 of both shacl tles'extend"in the same direction and these shackles are adapted to be engaged with the clincheriianges of the rim.

It will be noted from Figure 3 that when the shackles 15 are disposed in approximate alignment or at only a sligl1t angleto the links 11 that the inner edges oi'the eyes'19,

which inner edges are defined by the slotlS, bear against the shoulders or annular end faces Q tfformed bythe intersection o't'the reduced portion 23 with the enlarged cylin-.

drical portion 22 so that the. shackles 15 cannot he slid laterally ineither direction, and when both shackles are engagedu-pon the single rod" 23 the same result is secured and both shacklesare held from any; lateral movement with relation to the bar 23 by the edges of the shackles bearingagainst the shoulders 2 1.- Theseshackles cannot be shifted out'ot engagement'with the shoulders by reason of thelittle cross bar 20' which at all timesbears against the peripheralfaces of the eyes 13 and, therefore; constantly holds the eyes 19 in the reduced portionso'l the pin 21 'VVhen', however. the shackles 17 are forced toward the hooks llfthe spring bar 20 will be depressed, thus permitting the shoulders 0n the portion 22 to slippast readily detached to permit the ready reversal of the shackles with relation to the chain so that when these chains become so worn on one side as to be useless the shackles may be reversed so as to permit the other sideot' the chain to be directed outward and the smooth side of the chain to be disposed against the tire.

This the binder may bc used with or without an inner tire, boot orotherinate- 'ial,and in actual practice the construction is such that a :small tire iron may be inserted directly above the hinge connection between the hook and the link 11 and used as a lever to cinch-the chains over the tire, in the same operation forcing the shackles over therim where they maybe placed in correct position by the use of a'screwdriver or similar tool. It will be seen, .as before stated, that the construction of the hinge is such as to facilitate the'easy reversal of the chains or hooks. y i v A device of this kind has been found to be very effective in actual practice, may be cheaply made, andis readily applied or detached.

I claim 1. In a device of the character described a link and a-inember for engagement therewith, the link having an eye and the member being formed to provide two aligned laterally spaced eyes between which the first named eye-is received,a pintleextending transversely through all of said eyes, the pintle having a shoulder normally preventing its lateral movement out of engage- 'ment with one ot'said eyes, and a spring extending parallel tothe .pintle and urging the pintle in a direction to carry the shoulder into engagement with the wall of said last named eye.

2. in devices of the character described, a link and a ineniberfor engagement therewit-ln'the link having an eye and thewmemher being formed to providetwo aligned, laterally spaced eyes between which thefirst named eye is received, a pintle extending transversely through all ofsaid eyes and having a:should'er having a lengthequal to the distance between the two aligned :eyes ot said member, and aesprlng onsaldinember ur ing" the link outward and'theshoul- 'deredportion of the {pintle-into the-space between the aligned eyes of [sa d member,

tion of the 3. In devices of the character described, a link and a member torengagement therewith, the hnk havlng an eye and the member being formed to provide transversely aligned; spaced eyes between which the first named eye is received, a pintle extending transversely through all of said eyes, the

pintle being. formed intermediate its ends with a diametrically enlarged portion having shoulders at its ends and-having a length equal to the dlstance between the 111- ner edges of said aligned eyesln said member,- and a spring mounted upon said member extending parallel to thepintle and urging the eye of the link and the pintle outward and the shoulder lnto engagement between the aligned eyes of the member whereby to prevent any longitudinal movement of the pin.

4. In devices of the character described,

tween which the first named eyes are re-f ceived, a pintle extending transversely through. all. of said eyes and having a dia metrically enlarged portion formed to pro vide shoulders at the extremities and hav ng a length equal to the distance between the eyes on the shackle, and a spring carried by said shackle, and extending in the same planeas the pintle, said springbeing longitudinally concave and bearing "against the eyes of the links and urgingsaid eyes and the pintle out-ward with the enlarged porpintle between the eyes or" the shackle.

5. In devices of the character described, a

pair oi links, each formed with an eye, a

shackle for said links, the shackle being longitudinally slotted and formed to provide aligned eyes on each side of theaslot, the eyes of the link being disposedin said slot, andja pintle disposed through all of said eyes, the pintle having an enlarged cylindrical portion fitting within the eye of the links and between the eyes of said shackle and said pintle'having a reduced portion on each side of said cylindrical portion and loosely fitting within the eyes of the shackles, theshackle being provided at the base of its eyeswith a longitudinally extending resilientbar bearing against the peripheries of the eyes on the linksto'thereby-urgethelinks outward with reference to the hook and yieldingly hold theenlarged portion Pot the pintle "between the inner edges otthe eyes on the shackles.

In testimony whereof I hereunto aiiix-my signature.
